Abstract: The device (10) comprises a substantially stationary outer frame (14) and a movable inner frame (18) supported by the outer frame (14). The inner frame (18) is provided with a lower support plate (26) for a receptacle (C) containing the product to be mixed and with an upper clamping plate (30) which can be moved towards the inner plate (26) to clamp the receptacle (C). The lower and upper plates (26, 30) are both rotatably mounted about a vertical axis (Z). The device comprises a first electric motor (32), first driving means (38, 40, 42, 44, 45) arranged to impart a vertical oscillation movement to the receptacle (C) and second driving means (38, 40, 42, 58, 60, 56, 54, 52, 48, 26) arranged to impart a rotational movement about a vertical axis (Z) to the receptacle (C) at the same time as the vertical oscillation movement. The first and second driving means are both operated by the first electric motor (32).
